Predicted to enable transcription coactivator activity. Predicted to be involved in maintenance of protein location in nucleus and positive regulation of tyrosine phosphorylation of STAT protein. Located in mitochondrial intermembrane space. Human ortholog(s) of this gene implicated in retinitis pigmentosa with or without situs inversus. Orthologous to human ARL2BP (ADP ribosylation factor like GTPase 2 binding protein). [provided by Alliance of Genome Resources, Apr 2022]
